I have a few miscuts of the semi high series (series 6) for 1961 but am looking for any that members may have, so that a reconstruction of the slits can be attempted. If any wrong backs or partial panels are known, please share!!
The series 6 printing has 77 cards (447 to 522, plus a repeat of checklist 6). The checklist 6 variation printed in this series was the one where Aparicio's name was spelled "Louis" and I think the checklist 7 variation was the one where the copyright symbol is over the player's cap rather than over 2nd base.
